UCP-WC Clivet air conditioners are energy efficient modular units, direct expansion water cooled condensing units complete with precision adjustment. They are specialised in climate control for technological areas with a high thermal load and continuous cycle operation, such as Data Centres, Telecommunication stations, Laboratories and Processing sites. The UCP-WC technological solutions include electronically controlled ventilated sections, electronic thermostatic valve and different size compressors connected to the same chilling circuit or two separate chilling circuits with a single compressor. They contribute to reducing operational costs and the environmental impact of the site, thanks to the efficient use of the available energy and simplification of maintenance operations. The Twin Cooling version with additional chilled water circuit also allows an additional increase in the safety level since it is possible to count on two distinct and independent sources. The Economy Cooling version instead allows both increasing the safety level and exploiting the most advantageous energy source thanks to the additional chilled water circuit capable of integrating or replacing the direct expansion circuit.
